Novel soldering structure for capacitors

Abstract

The utility model relates to the technical field of capacitor, concretely is a new type of welding structure of capacitor, this welding structure includes top cap subassembly and sets up bottom cap subassembly at one side of top cap subassembly, top cap subassembly includes first positive pole connecting piece and sets up second positive pole connecting piece at one side of first positive pole connecting piece, the end of second positive pole connecting piece is close to first positive pole connecting piece and is sequentially provided with positive pole post, filling seal circle, end cover, positive pole isolation sheet and positive pole top cap, the end cover is annular, and is provided with recess on the end cover, the end cover is clamped between positive pole isolation sheet and positive pole top cap. The new type of welding structure of capacitor realizes greater current collection welding area, guarantees structural strength, and shortens the distance of pole piece to current collection welding point, and strengthens the structural strength of capacitor negative pole, thereby reduces capacitor internal resistance, improves ripple current carrying capacity, increases capacitor life.
